Adjusted analyses controlling for age, race/ethnicity, income, education, health literacy, number of years with asthma, limitations in ADL and number of chronic conditions, beliefs about asthma controller medications.
In order to further account for confounding by health status and subsequent need of functional support, we stratified by poor health status (diagnosed with five or more chronic conditions or reported one or more ADL impairment). Adjusted stratified analyses were adjusted for age, race/ethnicity, income, education, health literacy, number of years with asthma, beliefs about asthma controller medications.
